Speaking of learning, you shouldn't be running 'du' and 'dpkg -l' with
sudo; they'll run just fine as a normal user.

Won't they have a hard time with directories and files that are not
readable by the normal user?

No. dpkg just queries /var/lib/dpkg/status, which is world readable,
and 'du' works perfectly well on non-readable files:

~$ cat /etc/shadow
cat: /etc/shadow: Permission denied
~$ du /etc/shadow
1 /etc/shadow

And does du also work with nonreadable directories?
